Question about 2000 Mitsubishi Montero Sport

3 Answers

Exhaust leak/problem My 2000 mitsubishi montero sport seems to have an exhaust leak. It happened the other day while driving. It is a loud noise like a hole somewhere in the exhaust. It seems to be coming from in front of the catalytic coverter somewhere. It sounds like a small aircraft when it is running. Also, I seem to have lose of power, meaning engine power. It will drive but slowly.

I've had three exhaust manifolds crack on my 1999 Montero Sport. It's relatively common from what I've told and have read. Check to make sure you don't have a cracked manifold by removing the heat shield on each side (cold engine) then check the castings.

I recommend replacing the exhaust manifold gaskets and the donut gasket as well. I would also inspect the cat for leaks and breaches on the sides as well to be safe.

This just happened to my car as well cost me 400 to get it fixed the loss of power and noise was all due to my spark plug blowing out of the housing they had to put in a piece to fix that gap plus the ignition wires it sounded like a real old VW van that was about to die but loud. maybe you'll be able to fix yours by yourself now i have a bad oxygen sensor they said let it go until i have to smog later this year also my 4x4 lights are flashing all seems to work ok but this is new i heard it can be a sensor but the reg shops diag wont show anything wrong will have to take it to the dealer (b.s.) to have them fix it. I think ill just let it go

Black smoke coming from tailpipe and underhood of my 2000 Mitsubishi montero sport


Black Smoke is unburned fuel, try a tune up to start with and replace the air filter. If it does not stop then check the injectors to make sure that one or more are not stuck open. You also must have an exhaust leak in the engine bay.

2000 montero sport: There's a loud squealing noise coming from the engine. What could be wrong?


Squealing is most common with loose or worn belts, I would start by replacing the drive belt on the front of the motor and go from there, Its easier to troubleshoot a squealing motor if you know that the belt or belts are good.

I have a 2001 Mitsubishi Montero Sport that has condensation and light white smoke coming out the back exhaust-what would cause this and how do I fix it?


If this goes away after warming up and driving for a while, dont worry about it .Its moisture that seeps in as exhaust system cools down, then when you start up water trapped in muffler boils off.

2001 Mitsubishi Montero Sport has smoke and condensation coming out of the back pipe-what would cause this?


It's trapped moisture in exhaust pipes, dont worry about it, unless car ovrheats and you have unexplained coolant loss and novissible leaks. this would be blown head gasket. Did you post this same inquiry more than once?
